Hi,
it's hard to give a definite answer without having the input-file (in
case the question persists, please send it to us). The fact that some
events exceed the original beam particle energy hints the following:
- do you use biasing in your input (e.g., leading particle) -> in this
case an event-by-event analysis is fluctuating by principle
- in general, doing this kind of analysis you might also be affected by
fission (very low for W though) and missing energy
cheers
Markus
